Biologinė įvairovė dažnai yra nepakankamai įvertinama planuojant ir plėtojant miestus; tačiau miestams tankėjant ar plečiantis poreikis saugoti miesto gamtą ir didinti biologinę įvairovę tampa vis aktualesnis. Gyvenamųjų namų renovacija tampa itin reikšmingu miesto plėtros sektoriumi siekiant tvarumo tikslų ir įgyvendinant Europos Žaliojo kurso nuostatas. Taigi biologinės įvairovės išsaugojimas pastatų renovacijos proceso metu ir po jo tampa aktualiu klausimu. Šiame tyrime daugiausia dėmesio skiriama biologinei įvairovei miesto gyvenamuosiuose rajonuose, užstatytuose sovietinio modernizmo daugiabučiais gyvenamaisiais namais, ir biologinės įvairovės išsaugojimo bei didinimo galimybėms pastatų renovacijos procese, atsižvelgiant į ekologinius, socialinius ir estetinius aspektus. Tyrime taikyti metodai – literatūros analizė, tyrimai vietose ir žvalgomoji sociologinė apklausa. Tyrimo rezultatai patvirtina, kad biologinės įvairovės aspektų integravimas į planavimą, renovacijos praktiką ir politiką yra svarbus ir potencialus siekiant sukurti tvarius ir gyvybingus gyvenamuosius rajonus. Žvalgomoji sociologinė apklausa atskleidė teigiamą apklaustų kauniečių požiūrį į miesto biologinę įvairovę. Stebėjimas vietoje Eigulių, Gričiupio ir Dainavos mikrorajonuose rodo pastatų estetikos pagerėjimą ir gyventojų sąveikos su gamta požymius, tačiau buvo ir tokių stebėtų teritorijų, kuriose trūko pakankamų viešųjų erdvių patogumų, o augalų rūšių įvairovė buvo ribota. Pastebėjimai rodo, kad greta vykdomų renovacijos projektų reikia ir toliau skirti dėmesio gyvenamosios aplinkos ir biologinės įvairovės aspektų gerinimui šiuose rajonuose.

The principal aim of this work is to prescribe creativity into the renovation and reconstruction process in architecture. This issue connects both petrified past and unknown future with the simple idea of preventing local heritage and Portuguese legacy. The field of our research and creative design will be the Rua da Madalena (Madalena Street) in Lisbon downtown – Baixa Pombalina. The case study and estimated results would serve as a prototype for more innovative thinking about renovation of urban tissue and buildings for similar examples. Following the latest economic trends, the rebirth of traditional forms of business and interest for local heritage, we will attempt to bound raw numbers with endless sources of our creative minds. This case study, presented in the Heritage versus Tourism Conference in Lisbon, in May 2016 would be a step-by-step, a “know-how” example for many streets with various ambient over the world. Hence, the architectural and aesthetic values would be presented first, mathematical marketing formula afterward. The equation would involve both tangible and intangible factors and would be our attempt to introduce creative thinking as a ground for concrete, visible consequences. Architecture is a field, where this attempt could succeed. [ABSTRACT FROM AUTHOR]

There are about 40 million square meters of flat roofs in Lithuania, such as home buildings, public and industrial buildings and others. The condition of flat roofs which were installed 20 or more years ago is amiss because of old technologies, poor materials witch were used then. That is why these roofs do not meet today's requirements. These days repair works compile about 70 % of all roofing works. However, during renovation of roofs mistakes occurs quite often because not all modernization options are used during the process. This article analyzes installation and renovation technologies of flat roofs, moisture migration and condensation in the roof structure, defects and their causes. The relevant issue is raised - the correct installation of renovated flat roofs, suggestions is introduced on how to design structure of the roof to prevent moisture accumulation and avoid defects. The aim of this article is to analyze the installation and renovation technology for the flat roofs and to perform moisture mode analysis. [ABSTRACT FROM AUTHOR]

District heating systems, which were developed during the period of planned economics, should be renovated to conform to market conditions, or otherwise these systems should be dismantled and changed with alternative heat supply solutions. Such solutions should be based on the analysis of the economic long-run heat supply costs, assuming the future costs of fuel and technological installations. The current investigation offers an economic viability analysis of the technological renovation in the heat generation sector on the basis of future investments, fuel, operation and maintenance costs and revenues from electricity generation, bearing in mind that the projects are to be implemented in the open market conditions.

Lithuanian school buildings constructed before World War II or during the Soviet period have many defects. Most of these buildings have problems such as excessive energy use for heating, windows that are not airtight when closed, defects in the external walls, moisture damage, indoor microclimate parameters which do not correspond to the hygienic norms, etc. As the bulk of energy is consumed for the heating of buildings, this point seems to be the most important in respect of energy savings. Problems appearing in school buildings as well as the results of audits in 30 Lithuanian schools which were supposed to be renovated in the year 2001 are discussed in the article. The loan of 80 million litas was set for the renovation of the educational buildings among 52 municipalities at that time. The distribution of the renovation works in the schools is presented. The direct connection between heat energy savings and the amount of investments for heat saving implementation in the schools is estimated. [ABSTRACT FROM AUTHOR]
